Drow Legecy Magic

You have inherited the innate spellcasting ability of your dark elf ancestors. You learn to cast detect magic on yourself at will, without expending a spell slot. You also learn to cast the following spells once without expending a spell slot: levitate and dispel magic. You regain the ability to cast these two spells when you finish a long rest.

Charisma is your spellcasting ability for these spells, and you cast them at their lowest possible levels.
